To all 'whom t may concern.'

Be it known that I, ALBERT A. DaNsMona, citizen of the United States of America, and resident of Brookline, in the county of Norfolk and State'of Massachusetts, have vented new and useful Improvements in f y Dispensing Tops for Receptacles, of which the following is a specification.v v

This invention pertains to dispensing tops for receptacles such for example as collapsible tops, bottlesor cans adapted. to hold paste, liquid, or powder and relates more particularly to dispensing' tops of that type wherein the cap, cover, or other closure member remains attached to the top during the dispensing operation.

Many substances commonly disiensed from tubes, bottles or cans provide with dispensing tops, and particularly pastes and ao powders, are injuriously affected by exposure to theair or moisture. The most common eect of suchlexposure is to harden or 'cake the exposed'material, making it unfit for its intended use and "blocking or clogging the apertures of the di ns' top.

Dispensing tops osizheuiiove type as usu# ally constructed provide a recess, cavity, or pocket in which a small portion of the maierial is exposed after the dis nsing o v'ration and after the closure of t e cap, an 'the material thus exposed as-above stated frequently hardens or Acakes so that when the top is again opened, it is diiiicult to di e further material therefrom. Moreover, the

' cover is in closed small portion of the contents of the container which is -exposed in such pocket or cavity may, from its nature, cause injury to sui-rounding materials or articles, as for example, if the container is carried inthe pocket or' packed in contact 'with articles fof wearing apparel. I

The princlilal object of the present invention is acco 'ngly to rovide a nsing top of such character t t when t cap -or tion the l: l .lc: A

orifice or aperture is completely'o thus eliminating cavities, pockets, or in -which portions of the extruded material may remain ex sed to the atmosphere durthe interva of dispensing operations. urther objects are to provideads ns intop -of the above character .ap licab e to co apsilile tubes, cans or bottles o the usual type, or which may alternatively forni-an inseparable portion of such containers, as well as to provide a top of simple construe.

`cordance wit tion capable of dispensing the material free# 1y and rapidly. y

In the accompanying dra gs several desirable embodiments of the invention are il- 60 lustrated and in such drawin Fig. 1 is a fragmentar si e elevation of a container of usual type aving a preferred form of ydisplensin'g top constructed in acthe presentinvention applied 05 thereto;

Fig. 2 is a vertical section on the line 2--2 of Fig. 1;

Fi 3 is a sectional viewy similar to that of Fig. 2 but showing theparts of the top as 70 positioned for the dispensing operation;

Fig.4 4 is a view in vertical section illw trating a modified form of dispensing top as applied to a bottle; Fig. 5 is a vertical-section of amodiiiedform of top; and f Fi is a view in vertical section showing the ispensing top as forming an inseparable art of a container. i -v Re erring to- Figs. `1 to 3 inclusive the numeral 1 indicates a container, such for exam le as a collapsible tube or can, 'pro vid with anexteriorly screw-threaded Th dis or channel 8. e nsingto rorcomrisesa body portin 4 whic irs screw'- threaded atits lowerend for Hg.- :n H with the screw threads of the neck f th container. -'This body portion is preferably reduced in diameter at its um part, pro-- viding a shoulder at 5 and lc'lindrical tubular rtion 6 which is extern y screwthrea of wh one or more lateral branch pas- 100 l .such as 11, 12 extend outwardly and open at the conical surface8.

. -The cap 13, lof tubular form, is provided with internal screw threads atM for enfag; los

ment with the threads of the cylindrica 6 of thebody portion. This cap referably terminates at its upper end in a sugstnn tillly a flat surface' 15 an the interior cavity of the capendsatsuchsurfaceinanopening151 of substantially thesanie diameter asthatof 110 theend surface 9 of the part 7. The interior sm'rface 16 of the upper part of the cap is substantiall 1s closed.

truded material. When it is desired to dispense material from the container the cap is unscrewed until it occupies the position shown in Fig. 3. This leaves an annular passage between the cap and-the conical surface 8 and the material from the container may now pass freely up through the channel 10, the passages 11, 12, the annular chamber between the cap and the' part 7, and out through the opening at 15". l

At the conclusion .of the dispensing operation the cap is returned to its original position and as the top surface l5 of the cover comes into the plane of the end surface 9 of the member 7 the opening at 15"L is entirely obliterated so that none of the extruded material -is left in a position where it may be exposed to the air or where it may cause damage toy articles with which the device may come in contact.

In Fig. 4 the container 2O is illustrated as a bottle of ordinary formhaving a neck 21 and a cork 22. The dispensing top comprises a body portion having a cylindrical part 23 adapted to be inserted in an opening in the cork 22. The-part 23 is provided with an axial channel or passage 24 and has an outstanding flange 25 which limits' its downward movement through the cork.I The upper part of the body portion of the top is externally screw-threaded at 26 and termi-A nates in a truncated conical end 27 having a fiat top 28. The passage 24 has branches 29, 30 which open at the conical surface of the top 27. A cap 31 is arranged to engage the screw threads at 26 and this ca has a `conical inner surface 32 adapted to t snugly against the conical part 27 when the cap .The operation of the top in this, case is the. same" as that of" the top above described, the only substantial difference being that the top shown in Fig. 4 is adapted for application to a cork rather than to the screw-threaded neck of a collapsible i 'screw-threaded for engagement -with Vthe tube or can.

Referring to Fig. 5, the container 40, which may be a collapsible tube or can, is shown as provided with a neck 41 externally body portion 42 of a dlspensing top. This body portion may, as in the previous in stances, be reduced in diameter at its upper part to provide a shoulder at 43, the upper part being externally screw-threaded*at,44.

In this instance, however, the body portion terminates in a cylindrical, externally 'screw-threaded part 45 instead of f the tapered or truncated conical portion disclosed in the preceding figures. l

A cap 47 has screw-threaded engagement with the threads 44 of the body portion and also with the external screw threads 46 of the part 45. The body portion is provided with a central passage 48 provided with the branches 49, 50 which open substantially at the base of the part 45. The upper end of the cap has a fiat surface, which, when the .cap is closed, is substantially Hush with the upper end ofthe part 45.

With this arrangement the cap is unscrewed untilitis entirely disengaged from the part 45 thus leaving a passage around the screw threads 46 for the material to be dispensed. 'At the end of the dispensing operation the cap is again screwed down so that the part 45 entirely fills the opening in the end of th cap.

The device shown in Fig. 6 is substantially identical as that shown in Figs. 1l

"figures the closure of the lcap completely obliterates the/dispensin orifice or aperture so that by the use of eit er of such orifices the principal object of the invention is attain d.

I claim:

' 1. A dispensing top for receptacles lc0111- prisin a nozzle terminating in a truncated conica end, the nozzle having a canal or passage opening at theconical surface of said end, and' a cap havin a conical inner surface adapted to fit snug y over the conicalV end of the nozzle, the end of the cap when closed being flush with the end of thc nozzle.

2. A dispensing top for receptacles comprising .a body portion provided with means for detachably securing it to the receptacle and having a truncated conical end imperferate at its extremity, said body portion having a passage leading therethrough and opening at its conical surface, and a cap having screw-threaded engagement with said body portion and having a conical inner surface adapted to fit snugly againstthe conical surface of said end.

3., A dispensing top comprising a body portion having a cylindrical, externally screw threaded part and a truncated conical end, said c lindrical part having an axial channel an the end having a lateral passage communicating with said channel and opening at its conical surface, and a tubular cap having an internally screw threaded part engaging the cylindrical part of the body V' portion and an inner conical surface adapted t0 it snugly against the conical surface-of the endlof the body portion.
